Stress analysis and vibration of elastic and viscoelastic systems (Composite materials and structures)
FY 2015-16
Summary
The first objective of this research program is to provide an integrated design and manufacturing procedure for the development of advanced composite structures that offer high performance, cost efficiency, low wastage, and sensing capability that can detect and locate the occurrence of damages in-situ. The second objective is the development of composite structures that have variation in fiber orientation within a layer (in addition to changes in fiber orientation across layers).
The work for the first objective will involve the incorporation of nanoparticles into the matrix resin of the polymer composites to enhance the fracture toughness, electrical conductivity, and thermal conductivity of the polymer matrix. This modified polymer matrix is then incorporated into long fibers such as carbon fibers, and glass fibers using a prepreg machine. The combined modified matrix and fibers will be processed using automated fiber placement machine to make composite structures of common shapes such as plates, shells or tubes. The use of machines for processing improves the uniformity of the material properties throughout the structure. The enhanced electrical conductivity of the materials will be utilized to provide sensing capability. This sensing capability will enable the detection and location of incurring damages while the structure is in operation (i.e. in-situ or in-flight damage detection and location). The advantage of this method as compared to current NDT technologies is that the material is sensitive at every point in the structure, which makes the sensing to be universal, rather than local.
The work for the second objective will involve the steering of fibers within a layer. This allows the ability to vary the fiber orientation not only across the layers but also within a layer. Optimizaton procedure will be developed to augment the capability of composite structures using this new approach. The use of automated fiber placement machine allows the manufacturing of such a structure. Testing will be done to validate the theories. Step advances for composite materials and structures developments will be made.
